On the Necessity of Phantom Fields for Solving the Horizon Problem in Scalar Cosmologies

On the Necessity of Phantom Fields for Solving the Horizon Problem in Scalar Cosmologies

We discuss the particle horizon problem in the framework of spatially homogeneous and isotropic scalar cosmologies. To this purpose we consider a Friedmann–Lemaître–Robertson–Walker (FLRW) spacetime with possibly non-zero spatial sectional curvature (and arbit...
